- Premium M35 Cobalt Grade: Constructed from High-Speed Steel containing 5% Cobalt (HSS-CO), these bits boast a Rockwell Hardness of 65-67 HRC. This advanced composition offers superior heat resistance and wear durability compared to standard HSS bits, making them essential for drilling through tough metals like stainless steel, high-carbon steel, and cast iron.

This bulk set includes 40 pieces in the 4 most commonly used fractional sizes: 3/64", 1/16", 5/64", and 3/32" (10 bits per size). You will always have plenty of spares on hand, ensuring your project never stops due to a broken bit.
- Fully Ground & Precision Balance: Unlike roll-forged alternatives, our bits are fully ground from solid material. This manufacturing process guarantees precise dimension accuracy, excellent concentricity, and a smooth dual-flute geometry that ejects chips rapidly to prevent overheating and clogging.
- Durable 118° Chisel Point: Features a classic 118-degree point angle that balances cutting speed with tip strength. This design is ideal for general-purpose drilling and provides better stability and longevity when working with hand drills or on materials where a sharper point might chip.
- Versatile Application: The straight shank design ensures a secure fit in standard drill chucks and collets. Finished with an abrasion-resistant bronze coating, these bits are perfect for DIY repairs, model making, jewelry crafting, and professional maintenance on metal, hard plastics, and wood.
